tolong dijawab..pakai cara.

Luas persegi pnjng = p x l
= 8 x 5
= 40 cm²

Luas layang' = 1/2 × d1 × d2
= 1/2 × 6 × 11
= 33 cm²

Luas sluruhny = 40 cm² + 33 cm² = 73 cm²

58) Diketahui = panjang diagonal₁ (layang - layang) = 7 + 4 = 11cm
                         panjang diagonal₂ (layang - layang) = 3 + 3 =   6cm
                         panjang jajar genjang = 8 cm
                         tinggi jajar genjang = 5 cm

      Ditanya = Luas bangun datar

      Jawab = L₁ = d₁ x d₂ / 2
                         = 11 x 6 / 2
                         = 33 cm²

                    L₂ = a x t
                         = 8 x 5
                         = 40 cm²
 
                    L = 33 + 40
                       = 73 cm²

Semoga membantu
